The Copernicus Land Surface Temperature Monitoring (LSTM) mission, a key component of the Copernicus Sentinel Expansion Missions, is designed to carry a high spatial-temporal resolution thermal infrared sensor for land-surface temperature observations. This mission addresses the priority needs of the agricultural community, particularly in improving sustainable water resource management and monitoring vegetation and crop growth. The spectral coverage for the instrument's VNIR/SWIR bands spans from 490 nm to 1610 nm. Materion Balzers Optics (MBO) was selected as the supplier responsible for the VNIR/SWIR filter assemblies and the VNIR/SWIR dichroic beamsplitter. This paper discusses the design, manufacturing, and characterization of the sophisticated dielectric optical coatings used for the bandpass filters and dichroic components within the LSTM project. The coatings are deposited using Plasma-Assisted Reactive Magnetron Sputtering (PARMS) technology, offering high performance in demanding spaceborne optical systems.
